I'm having trouble deciding between the Canon eos 20d and the digital rebel xt. Can someone with experience with both chime in and tell me all about them? I've been into photography for a while (shoot with a hand-me-down olympus om-g), just now starting to get serious with it. It blends perfectly with my graphic design carreer. So yeah, I've been looking at those two cameras, having a hard time deciding. So, any help would be great... even if it's a recommendation for another camera. Thanks in advance!
